Abstract
The utility model relates to a flow dividing value assembly for an engine. A fuel valve, an air valve and a flow dividing valve are all rotary valves; the middle part of the flow dividing value assembly is provided with a combustion chamber; the fuel valve, the air valve and the flow dividing valve can be periodically switched on with the combustion chamber in rotation; both the fuel valve and the air valve are provided with T-shaped passages; the flow dividing valve is provided with two L-shaped passages which are not mutually connected; one passage is periodically communicateed with a throughway of the combustion chamber and an air vent of a piston air cylinder, and the other passage is periodically communicateed with a throughway of an exhaust tube and the end of the piston air cylinder; an H-shaped water line groove is arranged on a cylindrical surface of a valve core of the flow dividing valve; an oil outlet of the fuel valve and an air outlet of the air valve have phase difference.
Description
The utility model relates to diesel engine gas distribution system field, particularly a kind of diverter valve assembly of diesel engine.
In diesel engine gas distribution system field, gas distribution system roughly is made up of main members such as camshaft, tappet, conical valves at present, and operational noise is also bigger, complex structure, manufacture cost height.Operational noise is also bigger, because the distribution effect is undesirable, makes piston hot merit utilization ratio low, does not have sealing work done condition during continuous burning, and oil inflame is insufficient, and the tail gas pollution of Pai Chuing is heavier simultaneously.
The purpose of this utility model is: a kind of rate of combustion height, fuel-economizing, energy cleaning of off-gas, the simple compact engine diverter valve assembly of structure are provided.
In order to reach the above purpose, the utility model is achieved through the following technical solutions:
A kind of engine diverter valve assembly comprises fuel valve, air valve, diverter valve, firing chamber, and fuel valve, air valve, diverter valve are rotary valve.The diverter valve assembly middle part is provided with the firing chamber, fuel valve, air valve, diverter valve can be connected with the firing chamber in rotation periodically, the spool of air valve and diverter valve chain respectively is connected in pto, the fuel valve spool links to each other with the air valve spool by the awl tooth, fuel valve and air valve all have "T"-shaped passage, and diverter valve has two mutual disjunct " L " shape passages; The one passage leads directly to the firing chamber and the piston-cylinder ventilating hole cycle communicates, and another passage periodically communicates with the straight-through piston-cylinder end that reaches of outlet pipe.Diverter valve spool cylinder is provided with " worker " font waterline groove.Fuel valve, air valve is staggered relatively and driven by same sprocket wheel, has phase difference between the oil outlet of fuel valve and air valve air outlet hole.
Advantage of the present utility model is: because fuel valve, air valve, diverter valve adopt rotary valve, make diverter valve assembly have adjustability and controllability, the sequential of distribution, phase place and amount are joined accurately, and the distribution effect is quite desirable.Can improve combustion efficiency, reduce operational noise.Diverter valve spool cylinder is provided with " worker " font waterline groove, has realized diverter valve cooling, lubricated and sealing effect, and part steam imports the work done cavity, realizes increasing the merit fuel-economizing; Another part steam is discharged with respective cylinder, cleaning of off-gas during discharge.Diverter valve assembly is simple and compact for structure simultaneously.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation.
Fig. 2 is a sectional view of the present utility model.
Fig. 3 is the utility model diverter valve spool schematic representation.
Fig. 4 is the utility model diverter valve spool " worker " font waterline groove schematic representation.
Fig. 5 is the utility model embodiment 2 a sectional view.
As shown in Figure 1 and Figure 2, diverter valve 1 assembly comprises fuel valve 2, air valve 3, diverter valve 4, firing chamber 5.Fuel valve, air valve, diverter valve are rotary valve.On air valve 3, the diverter valve 4 sprocket wheel 6 is housed respectively, obtains surely than transmission by pto; Fuel valve 2 links to each other with air valve 3 by a pair of awl tooth 7.Each spool and valve body cooperate accurate, and be radially, axial seal, lubricated good.Diverter valve assembly middle part is provided with firing chamber 5, and fuel valve, air valve, diverter valve are rotating under the respective drive separately, by the sequential of setting and phase place with the firing chamber connection or close.Fuel valve 2 all has "T"-shaped passage with air valve 3, and diverter valve 4 passages are two mutual disjunct " L " shapes.One passage 9 of diverter valve is straight-through with the firing chamber, intermittently communicates with the cylinder body ventilating hole of piston; Another path 10 and outlet pipe are straight-through, intermittently communicate with the cylinder body ventilating hole of piston.
As shown in Figure 3, Figure 4, diverter valve 4 spool cylinders are provided with " worker " font waterline groove 8, and diverter valve is in rotary work under the high temperature, feed water in the groove and form rapidly that high-pressure water vapor is lubricated, the coolant seal film.The formed steam synovial membrane of diverter valve partly imports the work done cavity, vaporized expanding acting rapidly; Another part steam is discharged tail gas with corresponding cylinder, and tail gas is purified.
Fig. 5 has provided another embodiment of the present utility model, and fuel valve 2 and air valve 3 are staggered relatively and driven by same sprocket wheel, and fuel valve 2 all has "T"-shaped passage with air valve 3, and diverter valve 4 passages are two mutual disjunct " L " shapes.There is phase difference between the oil outlet 12 of fuel valve and air valve air outlet hole.In firing chamber 5, be provided with spark plug 11.In the present embodiment, the composition member of diverter valve assembly still less.Diesel engine is started at low temperatures easily.
The gas distribution system (being made up of main members such as camshaft, tappet, conical valves) of engine diverter valve assembly described in the utility model and existing reciprocating engine is compared, and is simple in structure, convenient manufacturing process, and operational noise is obviously reduced.
The utility model can with the supporting use of swing-plate type motor of straight-cylinder type or ring cylinder type.
